摘　　要：本文在总结现代海底热液沉积矿物流体包裹体研究新进展的基础上,分析了当前利用流体包裹体所研究的主要科学问题,包括证实岩浆流体对热液系统的贡献,海底热液系统存在多元循环和多个端元流体混合,流体的混合和不混溶(或相分离)作用是矿质沉淀的两个重要机制;总结了当前流体包裹体实验方法的发展现状,指出存在的主要问题是受制于当前测试分析技术和海底采样能力,并由此提出流体包裹体在现代海底热液研究中应用的发展方向为:开拓流体包裹体的测试手段和开发热液区深海下潜和钻探装备能力等。On the basis of summarizing the new progress for the study of fluid inclusions in modern submarine hydrothermal precipitated minerals,we have analyzed main scientific problems in the study of fluid inclusions,confirmed the contribution of magmatic fluid to the modern submarine hydrothermal system,proved the fact that there are multiple circulations and the mixing of multiple fluid endmembers in the submarine hydrothermal system,and suggested that the mixing and unmixing(or immiscible phase separation)of fluids are two important mechanisms of the precipitation of hydrothermal minerals in this paper.In addition,based on the current research data,we have reviewed the development status of current experimental methods of fluid inclusions,pointed out that main existing problems of the research are limitations of current testing and analysis technology and seabed sampling ability,and suggested that to exploit key analytical methods of fluid inclusions and to develop capabilities of deep sea diving and drilling equipment in the submarine hydrothermal area will be the development direction for the application of fluid inclusion study into the research of modern submarine hydrothermal fluid in future.
